Support in Release 23.09.1

Scalability Support

The following table contains the details of scalability tested in this release:

100GE Flex Supported Transceivers

The following table details the supported transceivers for this release:

Operational Considerations

This section documents the operational considerations related to Skylight Flex 100 release 23.09.1.

Access Control List Considerations

The order of operation/matching of ACL rules is based on the order of the ACL configuration; a separate field/configuration to specify priority of the ACL is not supported.

ACLs associated with the port, when requiring modification, will have to be deleted and reconfigured with updated field value.

Addressed Issues

This section lists issues corrected in Skylight Flex 100 release 23.09.1.

Unable to generate tech-support file in Skylight Flex 22.01.5.

This issue has been fixed.

PM telemetry reporting timestamps are not aligned with the platform’s system time

It is aligned once at startup and time is drifting overtime.

This issue has been fixed.

[NETCONF and YANG Limitation] Information is incorrectly displayed in octet string

This issue is presently system-wide on all netconf-yang elements displayed as a string.

This issue has been fixed.

[NETCONF and YANG Limitation] Telemetry element is not shown configured as expected

This issue has been fixed.

SSH Cypher, MAC, Key Exchange are not aligned between port 22 and 830

This issue has been fixed.

The system time and the hardware time is not synchronized

There is a discrepancy between the current time on the telemetry and the system time displayed on the show clock command.

This issue has been fixed.

[MEF-10.3] Policy-map configuration unexpectedly changes following a firmware upgrade

As a result, the QoS feature is not functioning as intended.

This issue has been fixed.

Remote MEP status is shown as 'Up' while no valid CCM has been received

The xConnect fault appears to report correctly and the MAC address of the remote MEP is not populated as expected.

This issue has been fixed.

Loopback ping is not working after MSR over Y.1731 LAG

‘Provided MEP does not exist’ error message is displayed.

This issue has been fixed.

[LLDP] System Name TLV is unable to be saved or restored

This issue has been fixed.

[LLDP] CLI command shutdown removes all configurations on the LLDP module and releases all memory that has been allocated for the LLDP module

For this reason, when restarting (executing no shutdown command), the mandatory Management Address TLV gets removed.

This issue has been fixed.

[LLDP] Management Address TLV for In-Band address is appearing on all ports instead of the intended port

This issue occurs when the no shutdown command is executed before IP address configuration is complete.

This issue has been fixed.

After executing shutdown or no shutdown command on ports with SR4 transceivers, there is a delay before the protocol changes status or may become stuck in the wrong status

Skylight orchestrator will report inaccurate port protocol status as a result.

This issue has been fixed.

When using the tool yangdump, certain YANG files returned errors after correctness validation

This issue has been fixed.

[NETCONF Limitation] The NETCONF operation GET is only returning the device state information but not the running configuration data

This issue has been fixed.

[NETCONF Limitation] NETCONF command get-config is returning a void output; not matching the running configuration on Skylight Flex

This issue has been fixed.
